Long double vs. ANSI inconsistency

[Tomasz Kowaltowski <tomasz at ic dot unicamp dot br>]

I'm using the following gcc version distributed with RedHat 6.1:

  gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)

The test program (testlongdouble.c) was:

-----------------------------------------------
#include <stdio.h>

int main() {

  long double ld = 1.0/3.0;
  
  printf("%Lf\n",ld);
  
  return 0;
  
}
------------------------------------------------

Using

  gcc -ansi -Wall -pedantic -o testlongdouble testlongdouble.c 

it gives the following warning:

  testlongdouble.c: In function `main':
  testlongdouble.c:7: warning: ANSI C does not support the `L'
length                modifier

Why doesn't it issue a warning about the declaration of a "long double"
variable?  Doesn't seem to be consistent!
